Can I Use Regular Dish Soap in a Dishwasher?

(Short answer: Please don’t. Long answer? Let’s chat.)


So, You’re Out of Dishwasher Detergent…

Alright, picture this:
You’ve had one of those days. You’re tired. You just finished dinner, and your kitchen looks like it lost a food fight. You load up the dishwasher like a domestic rockstar, close the door, and—bam. You reach for the dishwasher detergent and… surprise! Empty. Nada. Not a pod, tab, or drop in sight.

Then your eyes wander. And there it is. That familiar bottle of regular ol’ dish soap sitting next to the sink, looking all innocent.

“Eh, it’s still soap, right? Same difference?” you think.
Spoiler alert: it’s not.

Let’s break this down, one bubble at a time.


What Happens If You Use Regular Dish Soap?

Okay, imagine your dishwasher is like a super-organized little cleaning robot. It’s designed to use low-sudsing detergent, spray hot water around like a pro, rinse everything off, and be done with it. Boom. Clean dishes.

Now… introduce regular dish soap. The kind you use in the sink. You know—the stuff that creates mountains of bubbles when you wash a single fork?

Yeah, it doesn’t go well.

The moment that door closes and the cycle kicks in, it’s like you just gave your dishwasher a ticket to Foamapalooza. We’re talkin’ bubbles. Everywhere. Like, out-the-door, soaking-the-floor, you-need-a-mop levels of bubbles. It’s basically a kitchen soap party, and not the fun kind.


Why Can’t You Just Use “Any” Soap?

I get it. It seems logical. Soap is soap, right?
Nope.

Here’s the tea:

  • Dishwashing detergent is specifically made for machines. It doesn’t suds up much, but it’s strong and efficient.
  • Hand dish soap (think Dawn, Palmolive, etc.) is designed to be sudsy. You want bubbles when you’re scrubbing by hand. They help lift grease and make you feel like you’re doing something magical.

But dishwashers? They hate those bubbles. They weren’t built to handle them. It’s like putting high-octane racing fuel in your lawnmower. Fun idea. Bad outcome.


But What If You Already Did It? 

Okay. Deep breath. No shame here. Mistakes happen. Maybe you were just trying to MacGyver a solution in the moment. Maybe it was 2 a.m. and your brain was on autopilot. We’ve all been there.

Here’s your emergency cleanup plan:

  1. Stop the dishwasher immediately. Seriously. Don’t let it finish the cycle or it’ll be a full-on soap tsunami.
  2. Open the door and check the damage. Brace yourself.
  3. Scoop out as much foam as you can. Towels, cups, bowls—whatever you’ve got. Just start bailing.
  4. Wipe the interior—especially around the door seals and the bottom.
  5. Run a rinse cycle (or two) with no detergent to flush it out.
  6. Bonus move? Add a bit of white vinegar to help kill the suds. It works like a charm.

Oh, and maybe throw a towel down in front of the dishwasher… just in case.


Is There a “Safe” Substitute?

Okay, you might be wondering, “What if I’m in a pinch? Can I make my own detergent?”
Well… kinda.

There are some DIY dishwasher detergent recipes out there that use things like:

  • Baking soda
  • Washing soda
  • Borax
  • Citric acid

But let me be super clear: none of them should include regular dish soap. Not even a little. I know the internet is full of creative hacks, but if the recipe calls for Dawn, just walk away.

Stick with detergent made specifically for dishwashers—or hit the store. It’s not worth the foam flood.


So What Should You Use?

Honestly? Just use what your dishwasher was made for. Detergent pods, powder, gel—whatever your model loves most. Most stores carry tons of options, including natural and fragrance-free versions if you’re into that.

Bonus tip: You don’t even need that much. People tend to overuse detergent, thinking it’ll get dishes “extra” clean. But really? Too much detergent can leave residue behind and mess with your machine long-term.


Bottom Line: Don’t Do It

Can you use regular dish soap in your dishwasher?
Technically? Yes.
Should you? Not unless you want to spend the evening cleaning up a bubble disaster.

Look, I get it. You’re trying to be efficient. Resourceful. Frugal. All good things. But in this case? It’s a trap.

Just hand wash until you can grab some real detergent. Trust me—your kitchen floor (and your sanity) will thank you.
